happrox(1)		GNU Triangulated Surface utils		    happrox(1)

NAME
       happrox	-  returns a simplified triangulation of a set of points using
       algorithm III of Garland and Heckbert (1995).

SYNOPSIS
       happrox [OPTIONS] < [input.pgm|input] > output.gts

DESCRIPTION
       This manual page documents briefly the happrox command.

OPTIONS
       This program follow the	usual  GNU  command  line  syntax,  with  long
       options	starting  with	two  dashes  (`-').   A	 summary of options is
       included below.

       -n N, --number=N
	      Stop the refinement process if the number of vertices is	larger
	      than N.

       -c C, --cost=C
	      Stop the refinement process if the cost of insertion of a vertex
	      is smaller than C.

       -f, --flat
	      Input is a flat file with three x,y,z columns  (default  is  PGM
	      file).

       -r Z, --relative=Z
	      Use relative height cost for all heights larger than Z.

       -k, --keep
	      Keep enclosing triangle.

       -C, --closed
	      Close the surface.

       -l, --log
	      Log evolution of cost.

       -v, --verbose
	      Display surface statistics.

       -h, --help
	      Display the help and exit.
